In 1648, Glauber turned into the first person to manufacture hydrogen chloride by warming a blend of basic salt and sulphuric acid in concentrated form. In 1810, Davy demonstrated that it is a compound of chlorine and hydrogen.

Manufacture of Hydrogen Chloride

Hydrogen Chloride is set up in the research facility by treating sodium chloride with concentrated sulphuric acid. The reaction blend, comprising of concentrated sulphuric acid and sodium chloride, is initially warmed to 420K.

Sodium bisulphate is acquired as a by result, which is insoluble. Subsequently, sodium bisulphate is further mixed with more sodium chloride and further warmed to a high temperature of around 823K to give dissolvable sodium sulfate and HCl gas.
